[`unused_io_amount`]: Lint with `is_ok` and `is_err`
Fixes#10132
changelog: Apply [`unused_io_amount`] lint to `is_ok` and `is_err` without checking read/write amount
prevents `len_without_is_empty` from yielding positive when `len` takes arguments besides `&self`
Fixes#9520

non-standard method signature

`invalid_regex`: Show full error when string value doesn't match source
changelog: [`invalid_regex`]: Show full error when parsing non-literals or regular strings containing escape sequences
Fixes#4170, the escape sequence there causes the span to be incorrect which will have caused most of the confusion
Add `multiple_unsafe_ops_per_block` lint
Adds a lint, which restricts an `unsafe` block to only one unsafe operation.
Closes#10064

[needless_return]: Remove all semicolons on suggestion
Closes#10182
Multiple semicolons currently breaks autofix for `needless_return` suggestions. Any semicolons left after removing return means that the return type will always be `()`, and thus fail to compile.
This PR allows `needless_return` to remove multiple semicolons.
The change won't cover the case where there is multiple line yet.
i.e.
```rust
fn needless_return() -> bool {
return true;
;;
}
```

`cast_possible_truncation` Suggest TryFrom when truncation possible
This fixes the last issues from https://github.com/rust-lang/rust-clippy/pull/9664 as the author seems to be inactive. The PR author was sadly kept during the rebase, due to the conflict resolution.
IDK if it's worth it do to a full review, I only added the last commit, everything else remained the same, besides a rebase.

Render missing generics suggestion verbosely
It's a bit easier to read like this, especially ones that are appending new generics onto an existing list, like ": `, T`" which render somewhat poorly inline.
Also don't suggest `dyn` as a type parameter to add, even if technically that's valid in edition 2015.
Whne SYSROOT is defined, clippy-driver will insert a --sysroot argument
when calling rustc. However, when a sysroot argument is already defined,
e.g. through RUSTFLAGS=--sysroot=... the `cargo clippy` call would
error. This tests that the sysroot argument is only passed once and that
SYSROOT is ignored in this case.
This is useful for rust-lang/rust to allow setting a sysroot that's
*only* for build scripts, different from the regular sysroot passed in
RUSTFLAGS (since cargo doesn't apply RUSTFLAGS to build scripts or
proc-macros).
That said, the exact motivation is not particularly important: this
fixes a regression from
5907e9155e (r1060215684).
Note that only RUSTFLAGS is tested in the new integration test; passing
--sysroot through `clippy-driver` never worked as far as I can tell, and
no one is using it, so I didn't fix it here.
Allow implementing `Hash` with derived `PartialEq` (`derive_hash_xor_eq`
This is a common pattern and is totally allowed by the `Hash` trait.
Fixes#2627
changelog: Move: Renamed `derive_hash_xor_eq` to [`derived_hash_with_manual_eq`]
[#10184](https://github.com/rust-lang/rust-clippy/pull/10184)
changelog: Enhancement: [`derived_hash_with_manual_eq`]: Now allows `#[derive(PartialEq)]` with custom `Hash` implementations

trim paths in `suspicious_to_owned`
This continues my path trimming spree. I'm not going to add yet another changelog entry, we should have one "trim paths in some applicable lints" entry instead.
